The side of the zinc die casting (depth 50 mm) was used for cutting. I could achieve the purpose because it is sufficient work with an accuracy of about 0.1 mm, but I think that it is difficult when the object is steel. The cutting edge of the company's four blades was better, so the impression that the turn of the two blades looks unlikely in the future.
The finish of the cut surface is not good. Shank 6 mm Blade Diameter 6 mm Suitable for the condition that the blade length is 30 mm but because the blade grooves (shallow) are shallow? Is it because it does not fit fundamentally? The finish is rough. If it is for Hitachi's aluminum, it will be very beautifully finished, but because the blade length is a bit short, it can not be used.
